FOX Factory Race Series 3.0 Internal Bypass Coil-Over (Pair) – Adjustable for Maximum Off-Road Performance

Experience Race-Proven Suspension for Your Chevrolet/GM 1500

The FOX Factory Race Series 3.0 Internal Bypass Coil-Over shocks are designed to bring race-proven performance and superior suspension control to your Chevrolet/GM 1500. These shocks use patented Internal Bypass technology and Dual Speed Compression (DSC) adjusters to provide superior handling, increased damping control, and excellent high-speed performance—all in a bolt-on kit for easy installation. Whether you’re tackling rough terrain or speeding through open trails, these shocks deliver confidence, comfort, and control.

Key Features of FOX Factory Race Series 3.0 Internal Bypass Coil-Over Shocks

Patented Internal Bypass Technology for Superior Damping
The Internal Bypass system in these shocks provides position-sensitive damping, meaning different zones in the shock give you different levels of support. This allows for a smooth ride during normal driving while progressively increasing damping force to control hard bottom-outs and prevent harsh top-outs. The Internal Bypass system uses bleed holes in the ride zone to allow fluid to bypass the main piston, delivering a balance of comfort and control when it’s needed most.

Dual Speed Compression (DSC) Adjustment for Custom Tuning
The Dual Speed Compression (DSC) adjusters let you fine-tune your suspension to your specific driving conditions. Whether you need to dial in your 1500 for heavy loads, challenging terrain, or spirited driving, the DSC adjusters allow for precise compression and rebound tuning, giving you more control over your ride.

Recirculating Reservoir Bridge for Efficient Cooling
The shocks are equipped with a Recirculating Reservoir Bridge that continuously circulates fluid between the finned external reservoir and the main shock body. This cooling system keeps the shocks performing at their best, even during extended periods of intense use, by reducing heat buildup and preventing performance fade.

Built for Durability and Performance

Lightweight, Corrosion-Resistant Aluminum Body
The 3.0" hard-anodized aluminum body is impact-extruded and CNC-machined for maximum durability while being lighter than steel. The Type III anodization adds an extra layer of protection, preventing corrosion and wear over time, making these shocks highly reliable in tough off-road conditions.

High-Flow Race Piston for Maximum Performance
The race-developed high-flow piston design ensures optimal oil flow, providing better suspension performance and a smoother ride across rough terrain. This advanced piston technology helps maintain consistent performance under high-stress conditions, giving you the confidence to push your vehicle harder.

Advanced Sealing System for Extreme Conditions
The shocks feature a redundant sealing pack system, which includes a main seal, wiper seal, and scraper seal. These seals keep dirt, debris, and moisture out, ensuring the shocks operate smoothly even in harsh environments.

Frequently Asked Questions (FAQ)

Q: What makes the Internal Bypass technology unique?
A: The Internal Bypass technology offers position-sensitive damping, meaning the shocks provide softer support for normal driving and progressively increase damping force as needed. This results in better control during extreme impacts, while still providing a comfortable ride during everyday use.

Q: How does the Recirculating Reservoir Bridge improve cooling?
A: The Recirculating Reservoir Bridge continuously circulates shock fluid between the main body and the finned external reservoir, helping to keep the shock cool and preventing heat buildup. This ensures consistent performance, even during extended off-road drives or high-speed runs.

Q: How do the Dual Speed Compression (DSC) adjusters work?
A: The Dual Speed Compression (DSC) adjusters allow you to fine-tune both low-speed and high-speed compression, making it easy to optimize your suspension for different driving conditions. Whether you're carrying heavy loads or tackling challenging terrain, the DSC system lets you customize the ride to your liking.
